Expert Tips for Perfect Texture

Bake Potatoes Instead of Boiling: Less water = better texture.
Avoid Watery Filling: If your potatoes seem wet, cook mashed potatoes on low heat 2–3 minutes.
Prevent Sinking Topping: Use softened butter, not melted.
Make It Extra Smooth: Use a potato ricer or fine mesh strainer.
